WIRING
WIRING CONNECTIONS
All conductors should meet voltage and current ratings for each terminal. Also,
cabling should conform to appropriate standards of good installation, local codes
and regulations. When wiring the module, use the numbers on the label to identify
the position number with the proper function. Strip the wire, leaving approximately
1/4" (6 mm) of bare wire exposed. Insert the wire into the terminal, and tighten.

LEDS
STS – STATUS LED
The Status LED is a dual color LED that provides information regarding the
state of the module. This includes indication of the various stages of the start-up
routine (power-up), as well as any errors that may occur.
Startup Routine
Rapidly Flashing Red
Module is currently being flash upgraded. This
occurs for four seconds during a power up.
Steady Red
Module switching to configuration.
Green
Module performing normally.
Error States
Solid Red
Module not controlling, and not communicating.
Green/Pulsing Red
Module is controlling properly, but has lost
communication with the RD500.

FIRMWARE UPGRADE
The module's firmware is stored in flash memory so that software/hardware
conflicts are avoided, and so that software features may be added in the future.
During a download, RD500 software compares its own library of firmware files
with those stored in the RD500 module. If they do not match, RD500 software will
download the necessary files. The RD500 then checks to make sure that the I/O
modules contain the same firmware. If they contain a different revision, the RD500
will automatically copy those files into the module's flash memory. During this
process, the module LEDs will flash rapidly, starting with the top row, and
progressing through the remaining rows until the process is complete.
